On April 26, 1986, Reactor 4 at the Chernobyl Nuclear Power Plant near the town of Pripyat, Ukraine exploded. The explosion took place around midnight while the neighboring town of Pripyat slept. 4 workers were killed instantly. Four days later, the residents of Pripyat were ordered to evacuate. The residents never returned and the town still remains uninhabited to this day.
The Chernobyl disaster was a nuclear reactor accident at the Chernobyl Nuclear Power Plant in Ukraine, then part of the Soviet Union. It is considered to be the worst nuclear power plant disaster in history and the only level 7 instance on the International Nuclear Event Scale. It resulted in a severe release of radioactivity into the environment following a massive power excursion which destroyed the reactor. Two people died in the initial steam explosion, but most deaths from the accident were attributed to radiation.
On 26 April 1986 01:23:45 a.m. reactor number four at the Chernobyl plant, near Pripyat in the Ukrainian Soviet Socialist Republic, exploded. Further explosions and the resulting fire sent a plume of highly radioactive fallout into the atmosphere and over an extensive geographical area. Four hundred times more fallout was released than had been by the atomic bombing of Hiroshima.
The plume drifted over extensive parts of the western Soviet Union, Eastern Europe, Western Europe, Northern Europe, and eastern North America, with light nuclear rain falling as far as Ireland. Large areas in Ukraine, Belarus, and Russia were badly contaminated, resulting in the evacuation and resettlement of over 336,000 people. According to official post-Soviet data,about 60% of the radioactive fallout landed in Belarus.
